In order to obtain the fundamental informations on the variation of protein and amylose content in rice grain, 4 varieties were subjected to the 5 different harvesting with 5 different plantings. Amylose content in the rice grain were increased by later planting. Protein content of thermo-sensitive rice varieties were decreased while those of photo-sensitive varieties were increased by delayed planting. Interactions among planting date, variety and harvesting date were highly significant for amylose content, but not significant for protein content.
